We take SHA1 or MD5 algorithm to work around for converting your password to hash.

Initial chamber

Step 1: Open Visual Studio 2010 and create an empty website. Give it a suitable name [hashpass_demo].

Step 2: In Solution Explorer you will get your empty website, then add a Web Form by going like this –

For Web Form:

hashpass_demo (Your Empty Website) - Right Click, Add New Item, then Web Form. Name it hashpass_demo.aspx.

Design chamber

Step 3: Now make some design for your application by going to hashpass_demo.aspx and try the code like this:

hashpass_demo.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<style type="text/css">
.style1
{
width: 258px;
}
.style2
{
width: 239px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>
<table style="width:100%;">
<tr>
<td class="style1">
Enter Your Username:</td>
<td class="style2">
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</td>
<td>
<asp:Label ID="Label2" runat="server"></asp:Label>
</td>
</tr>
<tr>
<td class="style1">
Enter Your Password:
</td>
<td class="style2">
<asp:TextBox ID="TextBox2" runat="server" TextMode="Password"></asp:TextBox>
</td>
<td>
<asp:Label ID="Label1" runat="server"></asp:Label>
</td>
</tr>
<tr>
<td class="style1">
</td>
<td class="style2">
</td>
<td>
</td>
</tr>
<tr>
<td class="style1">
</td>
<td class="style2">
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Submit" />
</td>
<td>
</td>
</tr>
</table>
</div>
</form>
</body>
</html>

Your Design looks like the following screenshot:

Code chamber

Step 4: Now it’s time for server side coding so that our application starts working. Open your hashpass_demo.aspx.cs file and code it like below.

hashpass_demo.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Security;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
string securepass = FormsAuthentication.HashPasswordForStoringInConfigFile(TextBox2.Text, "MD5");
Label2.Text = "Your Username is-" + TextBox1.Text;
Label1.Text = "Your HashPassword is-" + securepass;
Label2.ForeColor = System.Drawing.Color.ForestGreen;
Label1.ForeColor = System.Drawing.Color.ForestGreen;
}
}
